Canola varieties show genetic resistance to verticillium

Research in Manitoba has found some canola varieties, or canola lines in the development pipeline, have resistance to verticillium.

That’s a relief for canola growers because verticillium stripe has become a common disease in canola fields, at least in the eastern Prairies.

“I don’t know if they’re commercial (varieties) or not. The companies do not share that information with me,” said Dilantha Fernando, a University of Manitoba plant pathologist, who has been leading a project to understand genetic resistance to the soil-borne disease.

“They could be in the pipeline. They could be elite material. That part I don’t know. (But) this is good news for the (canola) industry.”

What insect threats are Minnesota corn growers facing, and what research is helping farmers stay ahead of them?

At the 2026 MN Ag Expo, University of Minnesota entomologist Fei Yang shared updates on three Minnesota Corn-supported research projects focused on insect monitoring, seed treatments, and pest resistance.

Current work includes statewide monitoring programs that use pheromone, light, and sticky traps to track key pests such as black cutworm, true armyworm, corn earworm, European corn borer, and corn rootworm. Researchers are also evaluating whether high-rate seed treatments provide effective corn rootworm control and studying the development of resistance in European corn borer populations to Bt corn traits.

These projects help researchers better understand pest pressures across Minnesota and provide farmers with practical information to support informed management decisions.
